Draft agenda of the Lumi Session Room: 4/1-007 Wolfgang Lohmann: Overview of luminosity measurements at ILC and CLIC Frank Simon: Optimum Lumi spectrum and required accuracy for a tt scan near threshold (webex) Lucie Linsen: How well do we need to know the luminosity spectrum at 3 TeV CLIC? Rina Schwartz et al.: LumiCal at CLIC and backgrounds (title will be confirmed later) Strahinja Lukic: The transition region between peak and tail, and the BHSE effect Ivan Smiljanic: Luminosity in the peak and its systematic errors Stephane Poss: Luminosity spectrum at CLIC, status and outlook Sergey Kananov: Alternatives to measuring the luminosity spectrum
